Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of the active site in an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction occurs.

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What does it mean for an enzyme to be specific?

Back

Specificity means that each enzyme only catalyzes one type of reaction or acts on a specific substrate.

Front

How do enzymes increase the rate of chemical reactions?

Back

Enzymes increase the rate of chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after a reaction, as they are not consumed in the process.

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme by binding to it and preventing substrate binding.

Front

What is a coenzyme?

Back

A coenzyme is a non-protein organic molecule that assists enzymes in catalyzing reactions.
